HOG-CONVEYER.

SPECIFICATION forming part of Letters Patent o. 621,116, dated March 14,1899.

Application filed September 4, 1897. Serial No. 650,693. (No model.)

To all whom it may concern,.-

Be it known that I, NATHAN MANDEL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hog-Conveyers, of whichthe following is a specification, reference being had to theaccompanying drawings.

Heretofore it has been the practice in slaughter-houses where hogs areslaughtered to attach a shackle to one of the hind legs of each hog andto suspend the hogs from an inclined rail by means of trolleys or hooksattached to the shackles. The inclined rail extends from theshackling-pen to the scalding-tanks, and as the'suspended hogs movealong in procession they are stuck by the sticker as they pass beforehim and in due time thereafter are dumped into the scaldingtank. Thismethod of handling hogs is objectionable for several reasons. Inthefirst place a number of hands are required in the shackling-pens ofthe houses where largen umbers of hogs are slaughtered daily, and atvseveral other stages of the operation other hands are required,-as indumping the hogs into the scaldin g-tank, removing the shackles, In thesecond place where ay shackle is attached to one of the hind legs of ahog and it Vis elevated to the rail by means of the shackle-chain itfrequently happens that the hog is jerked violently, bruising the hamsor otherwise injuring the animal.

The object of lmy present invention is to avoid the objections abovepointed out and to provide an improved apparatus for handling hogs inslaughter-houses so that they may be driven directly from the pens inwhich they are confined to the slaughter-pens and be delivered therefromautomatically to the sticker, and then be automatically dumped into thescalding-tank, by thisv means not only dispensing with a large number ofthe hands heretofore necessary, but avoiding the danger of injuring theanimals.

To this end my invention consists in providing a suitable carrier withmeans for receiving the hogs and holding them in a vertical positionhead downward in such manner l as to expose the throat to the sticker,the carrier being arranged to convey the hogs past the sticker to thescalding-tank.

My invention further consists in providing means'for automaticallydischarging the hogs into the scalding-tank and in certain otherimprovements, which will be pointed out in detail hereinafter.

In the accompanying drawings, Figure 1 is a plan view of one form ofapparatus. Fig. 2 is a longitudinal section on line 2 2 of Fig. 1. Fig.3 is a plan view of another form of apparatus designed forslaughter-houses of smaller capacity. Fig. 4 is a longitudinal sectionon line 4 4 of Fig. 3. Fig. 5 is an enlarged detail, being a sideelevation of one of the flasks. Fig. 6 is a vertical section thereof,and Fig. 7 isa plan view.

In the drawings, 8 indicates a carrier which, as shown in Fig. 2, is Ainthe form of a turn; table and is supported uponballs 9, running in atrack 10, supported upon posts 11, so that the carrier 8 turns readily.Arotary motion is given to the carrier by means of a vertical shaft l2,driven by a pulley 13 or other suitable mechanism, the shaft beingpreferably arranged below the carrier 8 and being keyed to the hubthereof, as shown.

14 indicates a series of flasks arranged around the periphery of theturn-table 8, said fiasks being arranged to receive a hog and hold it ina vertical position head downward, as shown in Fig. 6. To this end thelower portion of the flask is contracted, as shown at 15 in Fig. 6, theinside of the flask being tapered, so that the hog lis prevented fromturning around. The flask 14 is formed in two semicylindrical partsconnected at one side by hinges 1G and at the other side by a latch 17,which engages a pin 18, the latch 17 being hinged to one of the membersand the pin 18 projecting from the other member in a suitable positionto be engaged by the latch 17 for the purpose of holding the members together to hold the flask in closed position. The latch 17 is providedwith .a downwardlyprojecting arm 19, the lower end of which ispreferably beveled or bent at right angles, as shown at 2O in Fig. 5. Aspring 21, which is secured to one of the members of the flask at oneside of the hinges 1G and projects around said hinges and bears againstthe other member of the flask, as shown in Figs. 5 and 7, serves toclose the flask after it has been opened.

22 indicates a door with `which each flask is provided, said door beingarranged in the outer lower portion of the flask and being normallyclosed by a spring 23. The door 22 is to permit the sticker to gainaccess to the throat of the hog if he is unable to reach it with thedoor closed.

24 indicates an elevated chute which leads A to and terminates over theflasks 14. As shown in Fig. 2, the floor of the chute 24 at the end nearthe carrier Sis formed by aconveyer consisting in the apparatus hereshown of a bolt 25, running over pulleys 26. A deflector 27 is providedat the inner end of the chute 24. Said chute is of such Width that thehogs will be requiredV to move along it in single file, and theconveyer-belt 25 moves at a rate of speed proportionate to that of thecarrier, so that a hog will be delivered to each flask as it moves belowthe end of the chute, the defleetor 27 serving to properly direct thehogs into the flasks as theyare carried along by the conveyer.

2S indicates a scalding-tank, one end of which projects under the flasks14, as shown in Figs. 1 and 2. l

29 indicates a cam suitably secured upon a bar 30 (or in some othersuitable way) at a point about midway of the width of the scalding-tank,as shown in Fig. 1. The cam 29 is adapted to be struck by the lower endof the arm 19 of the latch 17 and to lift said arm, raising the latchand permitting the weight of the hog to spring apart the members of theflask, the hog being thereby discharged into the scalding-tank. As soonas the hog is discharged the spring 21 will close the flask, the latchautomatically rengaging the pin 18 and locking the flask in its closedposition.

The operation of my improved apparatus is as follows: The hogs aredriven into the chute 24, and when they reach the conveyer therein arecarried along in single file and are discharged head l'irst into theflasks 14. It is obvious that as the hogs fall into the flasks they willlie with the throat outermost in proper position for the sticker, whostands at the side of the chute 24 opposite to the scalding-tank. As thehogs are carried before him the sticker sticks them, after which theyare carried around by the carrier until they reach the scalding-tank,when the latch 17 will be tripped by the cam 29 and the hog dischargedinto the scalding-tank, his weight opening the flask as soon as it isunlocked. As soon as the hog is discharged the spring 2i closes theflask and the latch 17 automatically locks it, so that it is then inproper order to receive another hog as it passes again under the chute24.

'shown in Fig. 3.

The form of apparatus above described is particularly adapted forslaughter-houses where large numbers of hogs are slaughtered and'whereplenty of space may be secured. In smaller houses, however, where thequarters are cramped, instead of using a turn-table carrier, as shown inFig. 1, I prefer to use the form of apparatus shown in Figs. 3 and 4,wherein the flasks are carried by an endless belt 31, which is caused tomove in a horizontal plane by sprocket-wheels 32 33, as

as 32, is driven by a shaft 34, as shown in Fig. 4. In this form ofapparatus the flasks are supported partly by the belt 31, butprincipally by trolleys 35, which move around a track 36. Instead ofusing asheet-metal wall for a track, as shown in Fig. 4, an ordinarytrack may be used, supported in any suitable manner. In other respectsthe apparatus shown in Figs. 3 and 4 is similar to that shown in Figs. 1and 2, and its operation is substantially the same.

It will be seen from the above description that in my improved apparatusthe hogs require practically no handling whatever, as all 'that it isnecessary to do is to drive them into the chute 24, whence they areautomatically carried past the sticker and discharged One of thesprocket-wheels,l

into the scalding-tank. No shackles are used,

and as the fall of the'hogs from the chute is not great there is nodanger of injuring the animals.

I have described my improved apparatus in detail in order that it mightbe fully nnderstood; but I do not limit myself to the specific detailsof the apparatus described, as many modifications maybe made withoutdeparting from my invention, which consists, broadly, in combining witha carrier a plurality of flasks or other devices adapted to receive andcarry the hogs past the sticker to the scalding-tank, also in combiningwith such apparatus means for automatically discharging the hogs intothe scalding-tank, and in the more specific features hereinafterclaimed. My invention therefore includes all equivalent devices.

That which I claim as myinvention, and desire to secure by LettersPatent, is-' 1. The combination of a carrier, one or moreanimal-receptacles carried thereby, said receptacle being open at thetop to receive the animal and having a smaller opening at the bottomwhereby the animal is supported in the receptacle with its throatexposed, and means whereby the animal may be discharged from thereceptacle, substantially as described.

2. The combination of a carrier, one or more animal-holding flaskscarried thereby, said liask or'flasks being arranged to hold the animalin a substantially vertical position head downward, and having acontracted opening at the bottom whereby the animal is supported in thereceptacle with its throat exposed, said flasks being composed ofseparable members,
